I love building computers, and i already have a good idea for a build but i would like to see other peoples ideas, and maybe you guys can have fun with this also. So im asking for an AMD build for NO MORE than 915$ that will be used for only gaming and internet, nothing else maybe watching movies but thats rare. I have no preferences for anything and will be fine with unlocking things to better things if thats what you want to go for. As far as cases go, i dont like any raidmax cases except for the smilodon EB and i already owned that so nothing raidmax and nothing weird looking like a raidmax. Thanks and have fun

This will give you the best overall performance. You can get a GTX 580 if you go the AMD route, but then if you decide to add another one you're gonna be severely bottlenecked. That, and the GTX 560 Ti offers MUCH more bang-for-buck and much better over-clocking. The TwinFrozr II version can get to 950MHz Core/1900MHz Shaders and 4600MHz Memory easily. At those clocks, it's the same speed as a GTX 570. The Radeon HD 6950 2GB is typically a few percentage faster stock, but when both are OCed they're the same speed since the 560 has more headroom. You can unlock shaders on the 6950, but that only brings a 3% increase in performance. Additionally, you're still gonna be held in comparison to a 6970 because it has slower rated memory (5GHz vs. 6GHz) and the Core doesn't over-clock as much. Of course, the 560 Ti is MUCH better for folding and costs a bit less, too. The TwinFrozr version also runs much cooler and makes less noise than the reference Radeon HD 6950. The Core i5 2500K will give you much more processing power than a Phenom II X4 in everything and faster speeds than a Phenom II X6 1090T stock in everything but video encoding/3D rendering. Over-clock both, however, and the 2500K will win there too. That's without mentioning the 2500K is much more efficient, too. The motherboard will give you SLI support should you want to add another GTX 560 in the future, and the PSU will take it no problems. The case is tremendous for the price, too.

Good luck with your build.

EDIT: disregard some of the things I said. The GTX 560 Ti TwinFrozr II is 2% faster than the Radeon HD 6950 2GB at 1920x1200. That's without counting further over-clocking, obviously. The GTX 560 still has more headroom than the 6950.Edited by LOL_Wut_Axel - 4/17/11 at 1:06pm

Going to agree with LOL_Wut_Axel..in this budget, without an SSD, you can easily go Sandy Bridge..would look into his suggested build if I were you, but I know on the other hand that some people avoid Intel for the sake of it
